      Normative data for macular volume with high-definition spectral-domain optical coherence tomography (Spectralis)
      To establish normative data for macular volume by spectral-domain optical coherence tomography (SD-OCT) in subjects with no known retinal disease. In an academic institutional setting, 50 subjects (age range 20-84 years) with no known retinal disease, best-corrected visual acuity 20/20, and normal intraocular pressure were enrolled. The subjects were divided into 3 age groups: group 1 included subjects 20-40 years of age, group 2 included subjects 41-60 years of ...

    13. Intraoperative OCT improves ophthalmic surgery

      Intraoperative OCT improves ophthalmic surgery
      The most popular examination method in ophthalmology today is optical coherence tomography (OCT ). Traditionally, OCT examinations have been performed pre- and post-operatively in vitreo-retinal surgery. While this application of the technology has enabled outcomes to be measured and results to be documented, surgeons have not had the ability to incorporate the results to improve surgical treatments. But with considerable advances to OCTincluding high-definition OCT (HD OCT), 3D visualization , and adaptive ...

  3. Quotes about Heidelberg Engineering

    1. I am becoming a big fan of spectral-domain OCT, especially Spectralis [Heidelberg Engineering, Vista, Calif.]...To this point with time-domain OCT, I have not been convinced that you can use this technology to follow patients over time. Now, with the faster image acquisition and better axial resolution we see with SD OCT, there is better quantitative peripapillary retinal nerve fiber layer measurement for glaucoma management. The improved accuracy of the OCT segmentation allows for better long-term evaluation of patients.
